She has a new book coming out called Betty & Friends: My Life at the Zoo.

In it, she says she loves good zoos but that protesting and marching aren't enough to turn a bad zoo into one.

"I was really kind of appalled that a city like Los Angeles had such a poor zoo… I’ve never been a big demonstrator from the outside criticizing. I’d much rather get inside and help. So I started to work with the zoo and got hooked, and they haven’t been able to get rid of me since."

While many groups, including PETA, feel that zoos are cruel, offering only the basic needs for animals, Betty feels differently.

"Many people get very irate, say, ‘Animals should be in their natural habitat, they shouldn’t be in captivity.’ Well, in the meantime, we’ve taken much of that natural habitat away. It doesn’t exist anymore."

If you'd like to hear more of Betty's words of wisdom, you can check it out at any major book store.
